Buying a bone densitometer: five things worth asking first

Buying guide · QST Technologies · 13 Aug 2026

Bone densitometry is a long-life purchase — most units stay in service well past a decade — so the specification that matters is the one you will still be living with in year eight.

1. What is the actual daily throughput?

Manufacturer scan times are measured under ideal conditions. Ask what a full appointment takes including positioning, patient handling and reporting — that is the number that sets your clinic schedule.

2. Does it do body composition as well?

Many departments end up wanting lean and fat mass analysis after the fact. Adding it later is usually not possible, so it is worth deciding before you buy rather than after.

3. How is it calibrated, and by whom?

Densitometry results are only meaningful if the machine holds its calibration. Ask about the phantom routine, how often calibration is checked, and whether your supplier or the manufacturer handles it.

4. Will it talk to your PACS and reporting system?

Check the DICOM implementation properly rather than accepting "DICOM compatible" at face value. Ask for the conformance statement and have your IT team read it.

5. Who is on site when it stops working?

A densitometer out of service means rescheduled patients. Find out where the nearest engineer is based, what the response time commitment is, and whether parts are held in the region or shipped in.
